It was a slow-onset change that led to voluntary migration.

The Dust Bowl of the 1930s increased migration in the U.S. because it was a sudden-onset event that led to forced migration.

The Dust Bowl of the 1930s, which was a period of severe dust storms and drought in the Great Plains region of the United States, significantly increased migration in the country. To determine the correct answer choice, we need to consider the nature of the Dust Bowl and its impact on the population.

The Dust Bowl was characterized by a sudden-onset event consisting of severe dust storms and drought. These conditions caused the topsoil to erode and made farming nearly impossible, leading to significant agricultural devastation. As a result, farmers and their families faced extreme hardship and economic insecurity.

Considering these factors, we can eliminate the answer choices that refer to a slow-onset change. Instead, we focus on the ones related to a sudden-onset event. Now we need to determine whether the migration was forced or voluntary.

During the Dust Bowl, many farmers were forced to abandon their lands and livelihoods due to the extreme environmental conditions and the inability to sustain their farms. These circumstances left them with no other choice but to migrate in search of better prospects elsewhere. Consequently, the correct answer is: It was a sudden-onset event that led to forced migration.

Therefore, the Dust Bowl of the 1930s increased migration in the U.S. as it was a sudden-onset event that forced many farmers to migrate in search of better opportunities.
